Your car checks a lot of boxes. Matching numbers,fender tag and build sheet,great color,rallye dash,mostly original sheetmetal,and already in paint,4 speed super track pack car! The only box not checked is the shaker hood. I would guess the car is worth 75k as it sits,and maybe 125k to 150k when it is finished. if I were you I wouldn't sell it,you won't be able to replace it,and you know how good the car is under the paint.
